Certificate answered my questions before I asked
Water content and appearance were both on the sheet. I did not have to write in to find out.

No games with the pricing
Sale price is a real discount off a real retail number, not an invented anchor. Easy to verify against other suppliers.

Third-party testing is the point
Anyone can claim ninety-nine percent. Showing the chromatogram and naming the method is different.

Small order, same treatment

Shipping to Hawaii takes a while
No fault of theirs, but plan for extra days. Product arrived in good condition regardless.

Support knew the product
Asked a specific question about a blend's composition. The person on the phone knew the answer without transferring me.

Documentation survived the move
Switched institutions and needed old certificates for records. All still accessible by lot number.

Fourth order this year
At this point it is habit. Nothing has gone wrong yet, which is the highest compliment I have for a supplier.

Clear about what this is and is not
The research-use language is everywhere and stated plainly. I would rather deal with a supplier that is upfront.

Would use a subscription option
Ordering the same three items every six weeks. A standing order would save me the reminder.

Straightforward returns policy
Read it before ordering. It is written in plain language and it is short, which usually means they intend to honor it.
